Hi all,
i followed this article Transform SAP BW Queries into OData Service: Part 1 - Generation and Activation to redefine a bw query into a gateway service for my mobile app. the service is ok, i could retrieve the data. however if i want to store the data on my mobile app for offline usage, something bad happened. i used SAP Kapsel plugin to create my Hybird mobile app, and used its offline plugin to store data. But the plugin can't be working if the key on gateway service didn't have a max length assigned(Kapsel Offline does not work on Windows 8.1 with SMP SDK SP07 PL01). unfortunately the service redefined from BW Query has a ID as key, however this field didn't have a max length assigned.
i tried modified the ID filed, failed, can't change the max length property. then deleted the ID ,and create a new ID_NEW, failed, the metadata still showed no max length,even i have assigned the max length.
seems SAP has a conflict between these two product , BW Query to gateway, and Kapsel Offline Plugin. any advice will be helpful.
thanks,
Billy
the screenshot below shows the ID without max length. 0 means no max length. how can i generate a gateway service from BW Query ,meanwhile the ID has a max length assigned?
