How to compare table level changes what was published and current work in progress

user2029739May 12 2022

I’m using git as version control, what will be the best and easiest way to compare a table which was checked-in last time and I’m currently working on. My end-user expects to see what column has been removed and what column has been added to, in the report form. I’m using data modeller version 21, I tried to create 2 different relational models, one for release 1 and one for release 2 and did the model compare from the tools menu but the HTML report is not very user friendly
Any Suggestion

The rule you have described will work if "the order total" is an attribute on the Line Items entity, which is the parent of the PartsDetails relationship. If you are getting the error message described you should do the following:

1. check that the relationship text for Line ITems --> PartDetails is "the PartDetails"

2. check that you have a number or currency attribute with the text "the order total" on the Line Items entity.

3. If you are rely on an automatically created attribute, you should change the attribute to "the Line Items order total". If you include the text of an entity in an attribute, the automatically created attribute will be placed in the correct entity, and then the InstanceSum statement will be correct for the attribute.

Hi Frank, It is not working. If I flatten the structure keep 1 entity (line item details) under global, InstanceSum works fine. For nested datamodel relationship, instanceSum not working.

PathhibHW,

This is almost certainly becuase the rule is trying to create the attribute "the order total" on the global entity, in this case it cannot sum across all line items, all part details.

Have a look at my suggestions 2. and 3. make either of those changes and your rule should work.

Hi Frank, Thanks a lot. It is working now. Can you please share the scenario for "Reasoning across entity instances" ForScope statement. Thanks.

Answer

Glad to hear you got it working.

Due to quirks of our rule parser, you can't sum across a deep relationship structure in one rule using scope operations. However with a few itermediate attributes it becomes pretty simple.

To sum all the PartDetails of a quote. I would use the following two rules:

the line item's total = instancesum(the PartDetails, the PartDetails ItemPrice)

the quote's total = instancesum(the line items, the line item's total)

You have to sum the totals across one relationship at a time.

Cheers

Frank
