WIP BATCH : 261 after 521 goods receipt to blocked stock

Dear All,

i am implementing a Wip batch flow in our customer.

I try the step of documentations in a following scenary:

Operation 10

Operation 20

I have already setting the total parameter for to generate 521 type moviment during confirm of the first operations, but i can't to execute 261 moviment for Wip batch of previous operations.

Example

Operation 10

          Confirm->

                         261 Batch A01   +  521 Batch A02 (blocked stock)

Operation 20

           Confirm->

                          261 Batch A02   +  521 Batch A03 (blocked stock)    Error for missing stock batch A02

Is possible consume batch A02 through 261 moviments?

Is there any customizing setting to do ?

Thanks a lot

Daniele
