Problem Note 56746: The Expression Builder in SAS® Data Integration Studio incorrectly modifies expression content, which might result in run-time errors
 |  |  |  |  |
Text that you enter in an expression on the Mappings tab of any transformation might be incorrectly modified when you save the expression. Specifically, this problem affects text in the Libref.TableName expression, where the expression matches the Libref and TableName of a source table in the transformation. The expression is modified to just the TableName when you save.
This modification is caused by the Expression Builder incorrectly tokenizing the expression when a save is executed. The general intention of the tokenizer is to identify key words like column names and add qualifiers (such as Libref) if none are present.
You might encounter errors during job execution due to this removal of content.
To work around this issue, quote the string to prevent tokenization, and then use SAS functions to remove the quotation marks. For example, you would enter Libref.TableName as shown here:
