I am in a need to create an IDoc for a purchase requisition from scratch for message type PREQCR1, basic type PREQCR102. It seems I have most segments figured out but I am getting stuck to post an IDoc for one that has account assignment K-cost center and item category D-service. I am not using service nos., only the limits amounts. It's always giving me an error message that the an error occurred assigning data in segment E1BPMEREQACCOUNT but I cannot figure out what is causing the error.
Can somebody send me an example file?
