COM error in planning book after executing BAPI_POSRVAPS_SAVEMULTI3

Hello everyone,

I am wondering if anyone could help me out with the below error I've been getting in the planning book.

It happens after I manually execute a macro and attempt to open the selection.

I'm currently testing BAPI_POSRVAPS_SAVEMULTI3 and have been having trouble with the PR creation. To make things brief the function module retrieves PR data, deletes them, then creates the same PRs again (this may seem pointless but there's a long story to it). We do get the expected results (the PRs show up in the PB and product view) but we get the above error popup everytime the macro runs and I want to know if there is anything wrong in the process. Also the macro does not seem to be working when execute in the background mode (it won't yield results) and I'm wondering if this error has anything to do with it.

Your help would be greatly appreciated and I will reward points to anyone who can offer me some advice.

Thanks in advance.
