abap2xlsx downward compatibility

[ThisIsAUsername089]

Hello together,

one of our customers has a abap2xlsx version from 10 years ago installed on their system.
When we generate excel files with this framework we always get popup's like in this issue: #1137
and sometimes the formatting is lost.

So now my question is: When we upgrade the framework with the latest version, is there a possibility that any of the existing usages of the framework need to be adjusted due to changes of signatures in some methods for example, or is it safe for an upgrade without any adjustments ?

Thank you in advance !

It's difficult to say for sure. In all the latest fixes, we tried to make it downward-compatible, like here.

I recommend to test your programs using abap2xlsx after applying any fix.

Also, some parts of abap2xlsx depend on the ABAP version (ALV for instance), abap2xlsx may not work as expected if SAP does some changes.

NB: 10 years is very old, so I wouldn't be surprised that you find some incompatibilities.

You may install the latest abap2xlsx version, but with renamed objects to not conflict with the existing version and see whether it solves your specific issue. There are these tools, as far as I know:

• shrinked code of abap2xlsx in the demo/abap2xlsx package of https://github.com/sandraros/shrinker (disclaimer: I am the author)
