Differences in MRP from SyteLine (PROGRESS) to SyteLine (SQL)

SyteLine 7.04 service pack 11 added a new Material Requirements Planning (MRP) function that is based on the MRP function included with SyteLine (PROGRESS). In general, MRP in SyteLine (SQL) is much the same as SyteLine (PROGRESS) MRP. However, some changes were necessary due to the functional differences between the two. This topic lists the differences.

MRP Algorithm in SyteLine (SQL)

The planning algorithm used by MRP in SyteLine (SQL) is almost identical to the algorithm used in SyteLine (PROGRESS). SyteLine (SQL) MRP plans requirements in order by the lowest level in which the item appears in all current, job, and production schedule bills of material. That is, it plans all end items first, then all items at the next level, and so on, backward planning each requirement from the requirement's needed date to the item's lead time, batching together requirements needed at the same period of time. SyteLine (SQL) MRP generates planned orders and exception messages to help you implement an accurate plan.

MRP Business Process

Your process for using MRP should not change significantly in SyteLine (SQL). As in SyteLine (PROGRESS) MRP, you must still run the Current Bill of Material Processor and Job and PS Bill of Material Processor before running an MRP generation to ensure the low-level codes are correct.

SyteLine (SQL) MRP also offers these features found in SyteLine (PROGRESS):

• Use the Lead Time Processor to calculate manufactured-item lead times from the time values defined on the routings.
• Use the Material Planner Workbench or Order Action Report to view suggested release dates for your planned orders.
• Use the Material Planner Workbench or Planning Detail form to view exception messages and firm planned orders into jobs, production schedules, etc.

You can run MRP in Net Change or Regeneration mode. As in SyteLine (PROGRESS), Net Change mode plans only those items for which on-hand, supply, or requirements information has changed since the last MRP run (as tracked via the Net Change field on the item record). When you make a change to an item's on-hand, supply, or requirements information, the Net Change field on that item record is selected automatically and that item will be included in the next Net Change MRP run, just as in SyteLine (PROGRESS). Running MRP in Regeneration mode plans all items in the database.

The remaining sections in this topic list the differences in specific forms, fields, and other assorted differences. In some cases, there is not a direct mapping from a SyteLine 6 form or field to an equivalent SyteLine (SQL) concept; however, in most cases, there is some replacement concept.

The tables below list only those screens/forms/parameters that are titled differently in SyteLine (SQL) or are handled through some other function. If the form still exists in SyteLine (SQL) under the same name as in SyteLine (PROGRESS) (such as the Material Planner Workbench), it is not listed.
