Material Creation error- MM01

2076 Views

Dear Friends

I get the following error when i am trying to create a material. I have not used any exit as the message says. I have uploaded around 3000 materials using a BDC for the same material type and i did not get a single error. But when i am trying to create manually a material i am getting the below error. Please guide me how to solve it.

The internal number already exists

Message no. MM042

Diagnosis

All proposed internal numbers already exist in the database. This is probably due to an error in user exit MGA00002. However, in rare cases, this message may also be displayed if the user exit is not activated.

Procedure

If the user exit is activated, check its source code.

If the user exit is not activated, try creating the material again.

Thanks

Sam
