STRUCTURE Statement

The BOM Procedure

STRUCTURE Statement

STRUCTURE / options ;

The STRUCTURE statement lists the variables in the input data set (the Single-level BOM data set). You should specify the Part variable and at least one Component variable. All other variables are optional. In this statement, you can also explicitly specify the parts that are to be used as the level-0 items.

COMPONENT=(variables)
COMP=(variables): specifies variables in the input data set that name all of the components directly used in the item identified by the Part variable. These variables are also referred to as Component variables. The Component variables must be of the same type, format, and length as the Part variable. At least one Component variable must be specified.

NOTE: This variable is case-sensitive when it is in character format.
ENDITEM=(enditems): specifies the parts that are to be used as the highest level or level-0 items in the indented bills of material. In other words, this option can be used to construct indented bills of material for subassemblies. The values for enditems must be either numbers (if the Part variable is numeric) or quoted strings (if the Part variable is character). If you do not specify this option, the procedure uses all final products as end items and builds an indented BOM for each of these items.
ID=(variables): identifies all variables not specified in the COMPONENT=, LEADTIME=, PART=, QTYONHAND=, QUANTITY=, or REQUIREMENT= options that are to be included in the Indented BOM and the Summarized BOM output data sets. These variables are also referred to as ID variables. The ID= option is useful for carrying any relevant information about each part (identified by the Part variable) from the Single-level BOM data set to the output data sets. The ID variables cannot be named as Gros_Req, _Level_, Low_Code, Net_Req, On_Hand, Qty_Per, Qty_Prod, _Parent_, Paren_ID, _Part_, Part_ID, _Prod_, or Tot_Lead.
LEADTIME=variable
DUR=variable: identifies the variable in the input data set that contains the lead time information for the part identified by the Part variable. This variable is also referred to as the LeadTime variable. The lead time of a part is the length of time between recognition of the need for an order of this part and the receipt of the parts. The variable specified must be numeric. If you do not specify this option, PROC BOM assumes the lead time for each part to be 0. The information in the LeadTime variable is carried to the Indented BOM output data set. Moreover, the procedure creates a new variable, Tot_Lead, in the Indented BOM data set if this option is specified. See the "Indented Bills of Material Data Set" section for more information about the Tot_Lead variable.
PART=variable
ITEM=variable: specifies the variable in the input data set that names the parent item. This variable is also referred to as the Part variable. The Part variable can be either character or numeric. You must specify the PART= option in the STRUCTURE statement. All the information specified by the ID variables corresponds to the part identified by the Part variable. All the information in the Part variable, except the name of the variable, is carried to the Indented BOM and the Summarized BOM output data sets. The name of this variable is changed to _Part_ in both output data sets.

NOTE: This variable is case-sensitive when it is in character format.
QTYONHAND=variable
INVENTORY=variable: identifies the variable in the input data set that contains the quantity currently on hand for the part identified by the Part variable. This variable is also referred to as the QtyOnHand variable. The QtyOnHand variable must be numeric. If you do not specify the QtyOnHand variable, the procedure assumes that you do not have any items on hand. In addition, the default name, On_Hand, is used for this variable. The information in the QtyOnHand variable is carried to the Summarized BOM output data set if the SUMMARYOUT= option is specified.
QUANTITY=(variables)
QTYPER=(variables): identifies variables in the input data set that contain the quantity of items identified by the Component variables required to make 1 unit of the item identified by the Part variable. These variables are also referred to as the Quantity or QtyPer variables. The variables specified must be numeric and the number of Quantity variables must be equal to the number of Component variables. If you do not specify these variables, the procedure assumes that you need 1 unit of each listed component identified by a Component variable to make 1 unit of the parent item identified by the Part variable. If there is exactly one Quantity variable, the information in this variable is carried to the Indented BOM output data set. Otherwise, the output data set uses the default name Qty_Per.
REQUIREMENT=variable
GROSSREQ=variable: identifies the variable in the input data set that contains the gross requirement of the part identified by the Part variable. This variable is also referred to as the Requirement variable and must be numeric. If you do not specify this option, the procedure assumes that the gross requirement for all parts are missing except for the final products. All final products are assumed to have gross requirements of 1 unit. In addition, the default name, Gros_Req, is used for this variable. The information in this variable is carried to the Summarized BOM output data set if the SUMMARYOUT= option is specified.
