Inventory count for WM managed serialized material

Hello,

We have the following functionalities active in SAP:

1. Warehouse Management

2. Serialized parts

3. Catch Weight Management.

We are trying to determine how anyone has solved cycle counting for serialized parts in a system with catch weight management active.

When clearing count documents using LI21N SAP gives an error "Maintain Serial number for total quantity".

SAP's solution - OSS 559531 - is to use LI20 or report RLLI2100 to post these in the foreground and enter the serial number.

Unfortunately, L210 and this report seems to call MB11, which is incompatible with Catch Weight Management.

LI20 switches to MIGO and there is not data on the screen.

What are the best practices to:

1. count serialized parts in a catch weight managed system?

2. count serialized parts in a WM system?

Thanks,

Saurav.
