| # Calculate Assembly Part Requirements (tiapl2221m000) Use this session to calculate the assembly part requirements for product variants whose assembly parts are not yet allocated. Note You can only start the current session if your current %HC(tcGLCompany.tc,company) is defined as master company in the Assembly Planning Parameters (tiapl0100s000) session. The assembly part requirements are calculated for product variants that meet the following criteria: The requested offline date falls in the demand time fence, which is defined in the Assembly Planning Parameters (tiapl0100s000) session. The Assembly Parts Allocated check box is cleared. The To Be Deleted check box is cleared. The Assembly Status is Open, Planned, or Frozen. Note If you enter a Date outside the demand time fence, a warning message appears. Product variants that fall within de demand time fence can also fall within the allocation time fence. In that case the assembly parts are likely to be already allocated by Assembly Control, that is, by the Build Assembly Part Allocation (tiasc7240m000) session. If the parts are not allocated, or if not all parts are allocated, the assembly lines for which the parts are not allocated, are taken into account by the current session. Refer to the Product Variant - Assembly Lines (tiapl3520m000) session for the allocation status by assembly line. Assembly parts for which the Floor Stock check box is selected in the Assembly BOM and Operations (tiapl2520m000) session are not taken into account by the current session. The current session calculates the assembly part requirements based on segment schedules, which is a rough calculation useful for high volumes. The segment schedules appear in the Segment Schedules (tiapl4500m000) session. As opposed to the assembly part allocation that is carried out in Assembly Control, the current session calculates the requirements for all companies and assembly lines in the selection simultaneously. To ensure that the assembly part requirements are calculated according to the latest data, the current session first performs the following actions: Update segment schedules. The segment schedules are updated if changes are detected that affect the schedule, or if you selected the Update Segment Schedules check box. Update allocation status. The allocation status is read from Assembly Control and copied to Assembly Planning. The allocation status appears in Assembly Planning in the Product Variant - Assembly Lines (tiapl3520m000) session and the details of the Product Variants (tiapl3500m000) session. Generate product variant structures of the product variants that meet the selection criteria described previously. After the product variant structure is created, the Product Variant Structure generated check box is selected in the details of the Product Variants (tiapl3500m000) session. Note that the product variant structure is only generated if the External Product Variant Structure check box is cleared in the Assembly Planning Parameters (tiapl0100s000) sesssion. After these preparation steps, the assembly parts requirements are calculated for the selected product variants, and the requirements are transferred to Assembly Planning for all the related companies. The requirements are transferred, using files that store the requirements by company by date. The directory to which these files are written, is set in the Assembly Parts Requirements Directory field in the details of the Assembly Planning Parameters (tiapl0100s000) session. After the assembly part requirements are calculated and transferred, a completion report is created. If errors occurred, the Show Messages button is enabled.

If this check box is cleared, the segment schedules are only updated if a change is detected that affects the segment schedules. However, not all changes can be detected automatically. As a result, select this check box in the following cases: The line structure is changed. The plan period definition of the current scenario is changed, while the reference date is unchanged.
