Hello Experts,
We have a quite a few stories created by our FP&A user group, via drag and drop of local files (excel and csv). We have a requirement to reuse these data and if possible connect BW system for schedule refresh.
We understand that below are the limitations, which kind of sad as some of these stories are well designed on already cleansed data -
I already checked couple of Q&A threads and everywhere it is mentioned we can not schedule and we can not convert.
Wanted to check if there is any workaround to reuse data from these wonderful stories.
Thanks
Hello viraj_saha,
Couple of assumptions in your question are not entirely correct. For example
Here is how it works. When we create a story based on drag and drop, system end up creating a "dataset" (also known as embedded dataset). This will remain part of story and not available for outside consumption. Embedded dataset allow linking, refreshing, changing data source etc.
What it can not do -
Lets go through each limitations. Linked analysis and combine data (model level) is only possible if data reside in models or "dataset". Embedded dataset let you convert to "Public Dataset"
Open story > Data> Grid view> Convert to public dataset.
Post conversion, story and dataset are decoupled. Dataset becomes available for consumption in other models / stories (join). Good thing is, newly created public dataset remain linked to existing story and any change / update in dataset impacts the existing story. No remapping of stories required.
Now scheduled refresh will only be possible if we convert embedded dataset to a model. In general this conversion is not supported.
Here is the trick: Story > Data > Grid View> Click on Save > "Open with basic data preparation" > Publish to model.
Now you have a converted model created from a copy of the embedded dataset. Here you can link your BW system and schedule a refresh job.
Limitations: Once you switch to basic data preparation, data gets reset to initial state. All transformation added later are ignored. This means you have to recreate transformation before or after publishing to model. Unlike Public dataset conversion, existing story do not link to new model. This is a manual step. Difference in behavior, partly due to fact "Public Dataset" is a conversion process and "Publish Model" is a copy activity.
Based on your requirement you can decide if you need to convert to public dataset or to a model.
Hope this helps. Let us know if you have any query around this topic.
