I have searched in the forum and found some useful info and was able to build workflow to some extent.
I am somehow missing from which node output should i be connecting to the continental nodes for formatting and how do i write it back to the excel. All this process with in the loop, so that formatting happens along side of file creation. Attached are the workflow and sample data for quick reference.
to my understanding you should format your Excel file (sheet) inside a loop. So in each iteration between 2 Excel Sheet Appender nodes and second Appender and Merge Variables node you need to use Continental nodes. Wrap them up into Metanode to make it clean
Regarding XLS Control Table Generator seems it usually receives either Excel data or manually defined tags…
yes, I think so. From my understanding the XLS Formatter nodes extract the base data and each of the coordinates (like row number, col number). Then they give each of these cells that are now uniquely identifiable a tag (a label so to say) and then - using the coordinates and these tags - apply the formatting to the desired output file.
I tried to visualize this (have done this with some of my colleagues as well):
but considering workflow is outputting multiple files inside loop formatting process should take place inside it as well. Or start another loop that will go over each file/sheet and apply formatting but first seems more reasonable to me…
@Andrew_Steel 's suggestion is very good on how to connect the formatting nodes. The XLS Control Table Generators should be connected exactly like he illustrated. But you cannot have two XLS Formatter (apply) nodes. You rather connect each of the duplicated formatting instructions with a Sheet Selector, then merge them via XLS Format Merger and then apply only once (ensuring with flow variable connection that this is done after the last Sheet Appender). The entire thing can then be embedded in your existing loop structure for multiple files:
I feel this is getting better and better with all your inputs.
Coming back to the requirement, there are 2 things required, format column header and conditional format Exception Aging column. So i have added 3 more nodes based on the below links in the forum (sorry for making it more complicated… )
Also i would like to explain 1 parameter, i.e., most of the times any 1 sheet either T&E Queries or P2P Queries will have data the other will be blank[only header] (only in some cases both will have data). There is no issue for column header, but for conditional format, if the data is blank, i am not sure how 7, 8 and 9th nodes will handle this.
Did you already try whether your solution is generic enough to handle missing data? The XLS Background Colorizer node will not fail if the input XLS Control Table doesn’t have any cell with the specified tag. So I don’t see any problem.
Sorry for the late reply. I think you are right, i received only warning.
To my surprise i am facing problem where we have data. The 8th step in the flow may be causing the next node forcing to error as highlighted below. I have checked the configuration which seems to be correct. Is there anything i missing here?
Sorry for the late reply, I didn’t step by the forum these days.
What exactly do the warning in node 8 and error in node 9 say?
The screenshot of the table result of node 7 doesn’t look like it is a proper table to be converted to an XLS Control Table with node 8. This way, your rule engine is only affecting cell C1 (1 row, 3rd column). But maybe that is what you are trying to achieve. What about The node 9 configuration? Why not have the “applies to tag” configured to “Red” as defined in the rule engine?
Below is the warning comments for your quick reference.
WARN XLS Control Table Generator 0:87 Cells of a XLS Formatter Control Table shall contain comma-separated lists of tags. Tags are typically user chosen and speaking names, e.g. ‘header’ or ‘totals’. Valid tags do not contain any of the letters ';|+&?!’. This warning can be ignored for some special features, e.g. the ‘applies to all tags’ option of the XLS Border Formatter node.*
WARN XLS Control Table Generator 0:87 Warning: The generated table is not a fully valid XLS Formatter Control Table as it contains invalid characters in tags. See log for details.
Here, i am trying to do the conditional formatting for the column Exception Aging.
In that iteration, it has populated only 1 record, hence you see only 1 row, hope my configuration for node 7 is correct. I could not understand completely the tag selection, hence it was like that.
I have attached the workflow also for your reference to have clear understanding.
The root cause seems to be that you don’t craft a proper XLS control table. The attached workflow shows how that can be done in your case: Use XLS Control Table Generator in unpivoted mode, apply Rule Engine now defining a tag only for the column to analyze and your condition (missing for all other cells), pivot back to a wide layout via re-applying XLS Control Table Generator.
