MM COnsigment stock: Unable to issue against reversation

dear all ,

we are trying to prototype a MM consigment stock process.

we have done the following

1. Purchase info record is created as consigment

2. PO is created. while creating the PO, the net price is coming as Zero.

3. Migo was possble with item category as K and movement type as 101

4. Created a reversation

5. finally tried to do a goods issue with special indicator as K

we are getting error PO has zero price.

we have tried all known settings and the net price in PO is still coming as zero.

kindly let us know where the issue could be . what setting need to be modified.

regards
