I have created two sub-tasks for this ticket and included the implementation
plan. Please review them and share any suggestions for modifications. I will
proceed with the implementation once I receive your feedback.
> Enhance Raw Material Reservation in Manufacturing Module with Manual Lot
> Selection and Automatic Inventory Reservation
> ----------------------------------------------------------------------------------------------------------------------

> Key: OFBIZ-13244
> URL: https://issues.apache.org/jira/browse/OFBIZ-13244
> Project: OFBiz
> Issue Type: Improvement
> Components: manufacturing
> Affects Versions: Upcoming Branch
> Reporter: Yashwant Dhakad
> Priority: Minor
>
> The Manufacturing module currently has a limited raw material reservation and
> issuance process, affecting accuracy and flexibility. Materials cannot be
> reserved when a production run is approved — they can only be issued. This
> allows the same inventory to be promised across multiple runs, thus leading
> to conflicts, delays, and mismatches between system records and real usage.
> The system also enforces a rigid LIFO method, ignores configured substitutes,
> and doesn’t support manual lot selection. For instance, if multiple lots of
> the same raw material exist—some close to expiry or with better quality—users
> have no control over which one to issue.
> To address this, three key features are proposed:
> * Manual Lot Selection - Let users reserve and issue materials from specific
> lots through the UI, thus bypassing FIFO/LIFO.
> * Automatic Reservation - Secure inventory automatically at production
> approval using FIFO/LIFO, avoiding cross-run conflicts.
> * Substitute Issuance - Issue substitute products when primaries are
> unavailable.
> Together, these changes reduce inventory issues, improve accuracy, and bring
> the system closer to real-world manufacturing needs.
