Before processing the invoice, system checks whether Equipment charges (Demurrage/Detention/Storage) has been calculated based on the setup defined, which will be fetched while invoicing.

 

While clicking the button to process the invoice, if there are any pending charges to be calculated for a particular order, then system will not allow to proceed with Invoice and the below message will be displayed.

Equipment Charges needs to be calculated for the selected Orders. Cannot proceed with Invoice.

 

 

 

Demurrage/Detention/Storage Calculation

 

Once the above button (CONT) is selected, and if any container (demurrage/detention/storage) needs to be calculated, then Equipment Charge Calculation program will be used.

 

In the Header section, only the Charge Type and Container should be allowed to select. Other fields Voyage, Line, Vessel, Port, BL Number, Order Number has to be fetched automatically from the Invoice Entry workbench of the selected order if the equipment charges are already calculated.

 

All other program functionality are the same as EQP Charge Calculation.

 

Upon selecting the Calculate button, system will calculate Demurrage amount and insert the amount in the Equipment Charges (Equipment Section).

 

Upon selecting the Details button, the summary section will be displayed as mentioned in the EQP Charge Calculation program.

 

 

 

 

Example:

For a Container CTRU090900, DSFULL occurred on 01-MAY-2018 and MTIN has not occurred at first.

 

User has calculated demurrage till 20-MAY-2018 by updating the Calculation End Date to 20-MAY-2018.(Till future date demurrage has been calculated) and invoice is also created for the amount 1000 INR.

 

For the subject container, MTIN has occurred on 15-MAY-2018, which is less than the already calculated demurrage. User now needs to create Credit Note to customer to repay the excess amount which was invoiced already.

 

Total Demurrage days calculated                : 20

Demurrage Days                        : 15

Current Demurrage Amount                : 700 INR

Already Calculated Demurrage Amount        : 1000 INR

Balance Demurrage Amount                : 300 INR

 

 

Important Notes:

 

1.From the above example, excess demurrage has been invoiced for which we need to create Credit note to the customer for the excess amount. So while calculating equipment charge, if the amount gets displayed in Minus symbol (Eg: -300), then Credit note has to be generated.

2.This negative amount has to be fetched in the Invoice Entry – Charge section and when user selects the charge for invoicing, Credit Note should automatically be created.

3.Separate document type and document number has to be created for the credit with the container number for the excess amount calculated.

4.Document Type has to be fetched from the Document Type master based on the description Invoice Credit Note. Document serial has to be generated separately as like Proforma Invoice & Actual Invoice.
