Hello,

This error message generally appears when you have duplicate data in this case: category data.

In txn:SMW01, check for the category data and see whether there are duplciate records,

Generally, this happens when you have an user exit and appending same data once again.

Hope this helps!

Hi Hon,

In my scenario there was a customizing error regarding TAXes, I solved it checking mlan registries.

Have a close look on the error mine was: A key was used twice for multirow set type CRMM_PR_TAX.

Then check on SMW01 the segment that stores this info. and look for inconsistencies.

Pedro
