IBM Sterling Ideas
Shape the future of IBM!
We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:
Post your ideas
IBM is transforming its request for enhancement (RFE) process. The purpose of the transformation is to provide a more consistent experience for you to submit requests and to enable IBM product owners to respond to your requests more quickly. For more information click here.
Start by posting ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you, 1. Post an idea 2. Upvote ideas that matter most to you 3. Get feedback from the IBM team to refine your idea
Help IBM prioritize your ideas and requests
The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The offering manager team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.
Receive notifications on the decision
Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.
We need to have an option to set the character used in the NONE Special Value property in a type tree's field. The only way it works now is by setting the exact value to be evaluated to NONE. So, for example, if we are setting the NONE special value of a three-character long and a five-character long text fields to have <NULL> bytes instead of the default spaces and want those values to be evaluated to NONE, we have to set the NONE Special Value of the first field to "<NULL><NULL><NULL>" and the second to "<NULL><NULL><NULL><NULL><NULL>". There doesn't seem to be a way to just say that we want the default NONE byte of this field to be "<NULL>" instead of the default "<SP>" for text fields or zero for numeric fields. Of course this example is a simple one, but in our case we have over 1000 fields that range from 5 characters to over 500 characters, so setting the exact absolute value of all those fields doesn't make sense and will make the type tree extremely hard to maintain in case the copybook needed to be reimported, which happens twice a year anyways in this project.
Note: This needs to be applied without changing the padding characters. So for text fields, for example, the padding character to still be <SP>, or whatever character it is, and zero for numeric fields, and so on.

How will this idea be used?
Since setting the NONE Special Value of every single field in the type tree is hard to maintain, especially with the constantly changing schema, having this option to set the byte used for NONE Special Value instead of entering the full value will enable using the NONE property for our solution. As a result, we will be able to distinguish between NULL fields and blank fields (fields that are all blank, but shouldn't be dealt with as NULL. For example, a five-byte numeric field named "count" having value 00000 as should be a valid value and should be different from a null value, where we will get 5 <NULL> bytes)
