SAP Error Message - Details

• Message type: E = Error

• Message class: GB - Messages used by the Boolean code generator

• Message number: 558

• Message text: You are using two sets with the same ID: &

What causes this issue?

You are trying to use two different sets with the same ID in one rule.

System Response

The system uses the first set entered in both places.

How to fix this error?

You have three options:
Encapsulate the access to one of the sets in a rule (recommended).
Create a rule for this and insert it in the existing formula. Example:
Instead of the "COBL-KOSTL IN SET OR COBL-PRCTR IN SET" formula, use
"COBL-KOSTL IN SET OR REGEL" where REGEL contains the following:
"COBL-PRCTR IN SET"
Rename one of the sets (generate a new set with reference using
transaction <DS:TRAN.GS01>GS01</>).
If you want to replace a set with another set of the same name, delete
the corresponding set validation from the requirement/check/rule and
then save the changed object. If you then want to maintain the object
again, you can then redefine the set validation. The system then
displays a dialog box from which you can select the suitable sets with
the same name.
