Hi

Dear experts.

I need to a many Cancel the assignment Maintenance Item Of Maintenance Plan, and of course I am also familiar with the T-code IP02 that I have to do one by one. I am looking for another way, such as in bulk or LSMW or even introducing BAPI or FM .
Of course, I also tried with LSMW, but the record does not get the item number in T-code ip02, and as a result, the record will not be good.
It cannot be done with IP15 or IP18, etc...

In IP02, you can unassign items individually, but mass changes cannot be performed collectively. Even using LSMW, this is not possible because LSMW cannot identify the rows related to each item. The best way is to write a program with the help of ABAPers
