Single Location Processing

 

In single (standard) location processing, material is automatically deducted from the component part's SIR location, as defined in the Part Master Maintenance conversation.  Although you may manually record the issue of a component upon the receipt of its parent, SIR processing will automatically record the issue and update the component's inventory status.  Using this processing option requires a smaller number of inventory transactions than the manual requisition method.

Setup

There are two main steps to enable standard SIR processing:

·     You determine the location from which each component's inventory is relieved in the Part Master Maintenance conversation.  On the Change Control screen, you set the issue code to 'S' (simultaneous issue and receipt).

·     You must then enter a location into the SIR Location field.  Neither blanks nor 'NOSRLOC' ("No SIR Location") are valid entries for this field.

Component Processing

 

Example:

 

                                                                                A  MFG

                                                                                |                              

                                                                                B (Oper on BOM = 010)  B/T

                                                ______________|___________

                                                |                               |                               |

                                                C                             D                             E

                (BOM Oper = blank)                         (040)                      (050)

 

Reference Operation Numbers

When creating a manufacturing order for parent part A in standard SIR processing, the reference operation numbers for part A's components default to the operation number of the build-thru part.  Please refer to the example shown above.  These operation numbers are later used to calculate each component's balance left to issue.  If part B's operation number on its bill of material is 010, and its components C, D, and E each have reference operation numbers of blanks, 040, and 050 respectively, then the following is true: 

 

Operation number for C = 010

Operation number for D = 010

Operation number for E = 010

In standard SIR processing only, the operation number of build-thru part B takes precedence over the operation numbers of the component parts.  Thus, all operation numbers default to part B's operation number, 010.
