I need your help to undestand concept related to Transaction/Event Type. Having a look into customizing I realize that every Tcode which post material document is linked to Transaction/Event Type (for example MB11 has WA), is it correct? Transaction/event Type is used only to define number ranges?
Would it be possible to change Transaction/Event Key for a specific Tcode or are they SAP default?
I know that for every Tcode is possible to change Document Type to generate FI documents so what could happen having Tcode with Transaction/Event Type WA and Document Type WE?
Thank you in advance for your collaboration.
