%BOMRSUW: Summarized Where-Used List

%bomrsuw (	ROOT=root, IN=SAS-data-set, LEV=variable, COMP=variable,
	QUANTITY=variable, QTYPROD=variable, RID=variables,
	QTYUSED=qtyused, OUT=SAS-data-set, DROP=variables);

constructs a summarized where-used list for a given item referred to as the item Root, which lists all parent items in which the item Root is directly or indirectly used and the required quantities. Unlike the indented where-used list, it does not list the levels of manufacture (Cox and Blackstone, J. H., Jr. 1998). The parameters for this macro are as follows:

ROOT=root: specifies the part number of the item for which the summarized where-used list is constructed. This item is referred to as the item Root. You must specify either a number or a quoted string for the ROOT= parameter, depending on the type of the Component variable.
IN=SAS-data-set: names the Indented BOM input data set. The default value is the most recently created SAS data set. A null value is replaced by the default value.
LEV=variable: identifies the variable in the Indented BOM data set that contains the indenture level information. The default value is _Level_. A null value is replaced by the default value.
COMP=variable: identifies the variable in the Indented BOM data set that contains the component’s part number. This variable is referred to as the Component variable. The default value is _Part_. A null value is replaced by the default value.
QUANTITY=variable: identifies the variable in the Indented BOM data set that contains the quantity per assembly information. This variable is only needed in creating the default drop variables. The default value is Qty_Per. A null value tells the macro program not to look for the variable that contains the quantity per assembly information.
QTYPROD=variable: identifies the variable in the Indented BOM data set that contains the quantity per product information. The default value is Qty_Prod. A null value is replaced by the default value.
RID=variables: identifies variables in the Indented BOM data set that contain product structure information and are not specified in COMP= or QUANTITY= parameters. These variables are only needed in creating the default drop variables. If you do not specify this parameter or specify a null value, the macro program assumes the Indented BOM data set contains no RID variables.
QTYUSED=qtyused: specifies the name for the variable in the output data set that contains the quantity of the item Root used by the parent item identified by the Component variable. The default value is Qty_Used. A null value is replaced by the default value. The Indented BOM data set should not contain any variables with the name specified by the QTYUSED= parameter. Otherwise, the values of the variable with the name specified in the QTYUSED= parameter will be overwritten.
OUT=SAS-data-set: names the output data set that contains summarized where-used list data for the item Root. The default value is _BOMOUT_. A null value is replaced by the default value.
DROP=variables: specifies all variables in the Indented BOM data set that you do not want to be included in the output data set. The default value is the list that contains the variables specified in the LEV=, QUANTITY=, QTYPROD=, and RID= parameters, in addition to the _Parent_, Paren_ID, Part_ID, _Prod_, Tot_Lead, and Tot_Off variables, if they are in the Indented BOM data set. A null value tells the macro program to write all the variables in the Indented BOM data set to the output data set.

The Input Data Set

The input data set of this macro is the Indented BOM data set described in Input Data Sets. The following parameters specify the variables in the input data set that are required by the %BOMRSUW macro.

COMP=: A character or numeric variable that contains the part number of the component.
LEV=: A numeric variable that contains the indenture level information.
QTYPROD=: A numeric variable that contains the quantity per product information.

The following parameters specify the variables in the Indented BOM input data set that are used by the macro, if they can be found in the data set.

QUANTITY=: A numeric variable that contains the quantity per assembly information. This variable is only needed in creating the default drop variables.
RID=: Variables that contain product structure information, except for those specified in the COMP= or QUANTITY= parameters. These variables are only needed in creating the default drop variables.
DROP=: Variables that you do not want to be included in the output data set. These variables are optional.

The Output Data Set

The output data set contains the summarized where-used list for the item Root. This data set has the same variables as the Indented BOM data set, except for the variables specified in the DROP= parameter. The output data set contains a new variable with the name specified by the following parameter:

QTYUSED=: A numeric variable that contains the total quantities of the item Root used, directly or indirectly, in the item identified by the Component variable.

Macro Variable _BOMRSUW_

Upon completion, this macro defines a macro variable, _BOMRSUW_, which contains a character string that indicates the status of the macro execution. See Macro Variables for the possible values of this macro variable.

An Example

The following statement constructs a summarized where-used list for the item '1400' from the Summarized BOM data set as displayed in Figure 4.1.

%bomrsuw(root='1400', in=IndBOM, quantity=QtyPer, 
qtyused=QtyUsed, rid=SDate EDate LTOff Fscrap, 
out=BomOut6);

The summarized where-used list for the item '1400' is displayed in Figure 4.7. Note that a summarized where-used lists a parent item only once for the total quantity of the given component (the item '1400' in this example) used by the parent item. For example, the item 'LA01' uses $\text{[math]}$ units of the item '1400', $\text{[math]}$ units for making the item 'B100' and $\text{[math]}$ for making '1500'. However, the summarized where-used list displayed in Figure 4.7 shows that the item '1500' uses $\text{[math]}$ units of '1400'. This is because another $\text{[math]}$ units are used in the bill of material for the end item 'A101'.
