Upload initial stock negative (quantity and value)

Hi Experts, our team is working in a Retail Customer and our project goal is to migrate to a new Client in where we changed the local currency.

We are using a LSMW to upload the initial stock (quantity and value). Although stock negative in allowed in valuation area/plant/storage location and in material master data, movement type 561 doesn´t allow negative quantities nor negative values, and the customer needs that. We tried using movement type 562 and we achieved negative quantities but we haven´t have success with negative values, instead system registered value zero.

How can we register stock negative value and quantity during a data migration? Which movement type can we use? Any idea?

Thanks in advanced for your suggestions.
