Hello,
If you are processing component scrap while backflushing with MFBF transaction , posting of components for scrap takes place with 551 movement GI for scrapping.
Please refer KBA - 2029238 - Scrap component at MFBF
You choose the option 'Assembly scrap' at MFBF
No Good Receipt is saved, no movement type 131.
Components are posted with movement type 261.
If you expect the movement 551 instead of 261 for the components postings, then you have to use the following process:
Choose the option component scrap in transaction MFBF: that option means an additional consumption will be posted due to a component waste.
Select the component backflushing option plus the scrap component Icon.
Then components are posted with movement type 551.
For reporting S026 update please implement OSS note 1599025 - Repetitive Manufacturing Statistical setup : component scrap
1566765 - MF47: S026 updated on posting component scrap
Best Regards,
