The MTO job calculates the total recommended quantity (to be purchased) as the sum of all affected BOM position quantities; this corresponds to the total list quantity. The disposition rule can be used to round up the calculated quantity to get commercially available order quantities, or to add a safety margin for contingency or spare material.

The Total Recommended Quantity value is calculated by a function considering the Total List Quantity value and the disposition rule details.

The disposition rules can be defined on the R.10.22 Disposition Rules screen. You can assign disposition rules to the requisition templates on R.10.41; see Requisition Templates.

To define a disposition rule, enter the rule name in the Dispo Rule field and the descriptions in the Short Desc and Description fields.

The details of the disposition rules must be defined on the R.10.23 Disposition Rule Details screen.

Dispo rules can be used individually or grouped into dispo rule sets. A set is applied during an MTO job and must be relevant to the project phase. For example, you could use dispo rule sets for the project phases ‘Estimate’, ‘Intermediate’, and ‘Final Design’. Each set refers to different rule details. The ‘Estimate’ phase requires more additional material than the ‘Intermediate’ phase, and in the ‘Final’ phase the calculated quantities are almost exact so additions are not needed.

To define dispo rule details, first select a dispo rule set in the Dispo Rule Sets block on the left. Then select a dispo rule in the Dispo Rules block on the right. Now you can enter the details for the selected dispo rule and relevant for the selected dispo rule set.

Enter a sequence number in the Order Seq field.

With the assigned Where condition, you define how the MTO job finds the idents for which the dispo rule must be applied. With the Where condition, a SQL statement is created, which is used by the MTO job to filter the material corresponding to the dispo rule requirements. For more information see Where Conditions. To assign a Where condition, either use the LOV in the Where Condition field to select one or double-click in the field to open the A.60.06 screen, which displays all existing Where conditions for R.10.23. You can either select one of the existing Where conditions or create a new one.

With the next fields you specify how the additional quantity is calculated. The % field defines the percentage addition, the Min Addend field defines the minimum quantity to be added, and the Max Addend field shows the maximum quantity to be added. An entry in the Absolute field is used to add this exact value (not used in combination with the other fields). With the value in the Rounding field, you define to which exact values the calculated quantity should be rounded up.

For example, to add 10% to the calculated pipe length, but not more than 50m and not less than 5m, with exact pipe lengths of 12m, the dispo rule would be defined with these details:

  • % = 10

  • Min Addend = 5

  • Max Addend = 50

  • Rounding = 12

The Param Char 1 - 5 and Param Num 1 - 5 fields can be used within the CIP m_pck_req_custom.std_dispo_qty. The standard version of the CIP does not use these fields.

The disposition rule specified here and assigned to the requisition template on R.10.41 is applied only when processing an MTO job if the Dispo Rule option of the MTO job is set to ‘Common Rule’.
