Reverse backflush issue

[#1]

We have a CO production order for which the material is backflushed.Observed that movement type 131 has happened for the material.It is also observed that 531 and 261 movement types has also happened for some materials.How is the flow normally and how does it happen?The user was trying to reverse the backflush document when he faced the issue for a material saying deficit of stock in sloc.Can somebody explain the flow of this process and how these movement type like 131,531 and 261 appear while backflushing and what propbably could be the issue while reversing the document

The CO production order is created a material. In the BOM of the material we have only 1 material.However inside that material we have a set of other materials.Not sure how these materials are being picked up for Goods Movement

Hi Nevin,

If you have only one component(A) in the first level BOM, and the BOM components under A are getting  back flushed, it is obvious that the item A is set up as a phantom item.

At the time of back flushing, system explodes the BOM for the phantom item, picks the 'Actual' items under the phantom item, and posts goods issues.

--> you can check if the phantom indicator is showing up against A in the first level BOM

--> Material master for A should have special procurement key set as 50 (check MRP2 view)

Thanks

Hi Nevin,

You can check for phantom indicator set for the component at first level, and that will be the reason it got exploded and below level items picked for back flush as explained by Mr Senthil.

To reverse it you can cancel the material document or in MB1A you cancel with respect to order reference in the menu option selection.
