For a time split where the commercial length for each product in the split sums to the total length of the unit, you need to define ISCI codes first for each product/length in the split on the ISCI Codes Definition Detail window. Then you will create an overall ISCI Code for the total time length an using the Split Entry window add the partial length ISCI codes.
Key the Client and Length and also click Or Splits checkbox.
Click the Next icon.
On the Detail window add one or more rows using the Add icon.
Key the overall ISCI code and description for the length of the unit.
Click the <Split Entry> button to display the Split Entry window.
Use lookup to retrieve each of the individual smaller length ISCIs that will be used for the overall ISCI.
Click <Confirm> button to send them all to the overall ISCI on the Detail window. The Product codes for this ISCI will display *SPL indicating a time split.
Click the Save icon.
Return to ISCI Codes Definition to create other ISCIs.
