Minimum remaining shelf life value -- per plant

Dear All

Normally if batch is activated and Min rem shelf life has value, when you do a GR you will be prompted to enter expiry of the matl in addition to batch (under the batches tab).

Now we have a situation where a material is shared by several plants. In 1 plant they want to enter expiry date however the min rem shelf life for that matl is set to 0 which makes the system not prompt to ask for expiry date when doing GR.

how can I activate this feature (to make system prompt for expiry date) only for this plant.?

The minimum remaining shelf life value is in the Plant data / Stor 1. tab, however it is a MARA field. So if I just change this field it will affect all other plants as well which is not desired.

Any suggestion?

Thanks
