Data source Yield & Scrap (SCMYASU01) is providing the quantities of yield and scrap recorded for a production order. That means total confirmed and scrap quantities of each reporting point of production lot/order. However, Deviation reason(scrap reason) is a field at production confirmation level rather than production lot - reporting point level. For example: production lot - reporting point - RP01 has three production confirmations, CONF1,CONF2,CONF3.

CONF1 has 0 scrap quantity.

CONF2 has 1 scrap quantity with tool broken as scrap reason.

CONF3 has 2 scrap quantity with material damage as scrap reason.
Hence, Yield & Scrap (SCMYASU01) will not display anything in the scrap reason since there are multiples reasons from multiple confirmations, and it is not reasonable to display any one of them.

Here this data source only gives the reporting point level data with scrap and confirmed quantities but not confirmations level data.


This is standard behavior of data source Yield & Scrap. Please use standard report Confirmation Journal (SCMCFJU01_Q0001) to check deviation reason of production confirmation.
