I have a requirement to display in report for differnt movement types like transfers, issues and receipts.

The movement types for tranfers 411 412 , but I observed in MB51 that 411 text(+ sloc to sloc) and 411 text (- consignment to own) again considering +ve an -ve based on text from T156T (movement text table. but for some materials it is not set.

My doubt is How can I categrorize these values +ves and -ves. Which field(s) is I need to look.

Is there any field(s) to capture the movements within the plant and outside the plant?

Please help me........

Thanks
