Unable to see idoc in WE02 in ECC or GTS

Hello -

When I send an idoc to GTS for a material master change via program RBDMIDOC in SE38, I do not see the idoc display in WE02 in ECC or GTS. I see that some, but not all of the data which I changed in the ECC material master has been updated in the GTS Product Master and therefore know that an idoc is being generated and sent, but I want to troubleshoot it to see what data was and was not picked up and sent over. Since I cannot see the idoc that was generated in WE02 in either ECC or GTS, I am unable to do so.

The reason I am investigating this is that I am attempting to send over additional data (tax classifications) in the Reduced Message Type /SAPSLL/MATMAS_SLL, but the newly selected data is not picked up and sent over. I am trying to understand if this is an issue with configuration or the idoc itself.

Has anyone had any experience with this that can offer some insight?
