Reserve Issue Method

Hi Doretta,

As per the F1 document, following is the system behaviour,

• Issue Reserved Material

When the material line is reserved before it is issued, issuing will primarily be done from the reserved location(s), i.e., all reserved material will be issued before any backflush to try to find other locations to issue material from. Within the reserved location, material is issued from according to a certain priority order, such as FIFO (First In, First Out). This principle is not used if the material has an expiration date. In that case, the material with the earliest expiration date is issued first.

• Issue Material Manually

By manually issuing material, you ensure that you get exactly the material you want. When you use this method the backflush hierarchy and part parameters are ignored, and you are allowed to manually issue available material from locations of the floor stock, picking and production line types.

• Backflush Material when Receiving Shop Order

When you receive a shop order, the system will automatically backflush material that is not yet issued. Backflush hierarchy and part parameters will be used to find locations where material is allowed to be backflushed.

• Backflush Material when Reporting Operations

When an operation is reported, all material connected to that operation needs to be issued.If all material connected to the reported operation is not reserved or issued, the backflush hierarchy and part parameters will be used to find locations where material is allowed to be backflushed from or use this function to reserve material linked to a specific operation. By linking material to the operation in which it will be used, you do not have to reserve material too far ahead in time.

• Issue Over-Reported Qty

If material connected to an operation should be backflushed according to the reported quantity or up to the plan quantity when a shop order is over-reported, decides by the value of the Issue Overreported Qty check box. If unconnected material should be backflushed according to the received quantity or the plan quantity when a shop order is received with a higher quantity than the planned quantity, decides by the value of the Issue Overreported Qty check box.

Hi Dorretta,

In addition to the information shared on how each Reserve/Issue method works, below are instances you can use this option to affect method in general or for specific scenarios (i.e. for all shop orders or for a specific shop orders)
