Serial Number

[krome101]

I have a program that has package numbers in it, i want the customer number to go in serial number based on the package. In other words when i hit New Record, I want the "Customer Id field" to wait until a package number is selected in the "Package Field", when a package is selected, ex. Package "1A" I want the Customer ID Field to look up all the records that are 1A and look at the last records Customer ID number and add 1 to that new record.

So in other words, if I have 360 records on Package 1A and 210 records on package 1B, when i hit new record and then hit package 1A , i want the Customer ID field to show 361, if i hit package 1B i want the customer ID to show 211.

Please include a sample of the script code to be written. And if it is possoble to insert the script in the definition of the Customer Id field.

Please help, as this problem is driving me crazy.

Thanks

Max (Self by CustomerID::SerialNumber) + 1

It is a calculation, either scripted or autoentered. It looks for the Max value of SerialNumber (or whatever your field is called) through the self relationship (to the same file) via the CustomerID (or whatever the field is called).

This will get the max serial value for the customer and add 1 to it to generate the next serial number.
