Event controlled product substitution case in SAP IS Retail

Question

Requirement: Event controlled product substitution case
SAP System: SAP ECC 6.0 with IS Retail and without F&R and APO
To check for the available stock of original material and replace it with a FU/Replacement material if the stock is zero or less than the ordered quantity (in a STO).
We have done the following to achieve this:
1.     SAP IMG: Maintain Follow up Categories
Created a Follow up category number: 01
FU Category: Replacement material
Priority and Validity: checked
Check cycles: No check
2.     Using T code: WRFFUART, we have assigned a replacement material to a original material and provided validity period with priority 01.
Issue: While creating a STO or at the time of Delivery creation, the original material is not getting replaced with the substitution material (depending on the stock situation)

Answer 1

Hi,
is this issue still open?
Does the replacement article have stock?
Have you activated the substitution processing?
In the article substitution - application-specific control profile how have you maintained the parameter Quantity Control for Replacement Articles - Event Controlled? There will no quantity from the replacement product ordered when you use option 'Original Article with Available Quantity; If 0: Substitution Article with full quantity').
Kind regards,
Rainer
