Back IMDS Errors and Warnings
In this document you find the IMDS Steering Committee position concerning rejections of MDSs with Warnings in IMDS.
Here you can download the error code list in IMDS and how to fix them:
List of Errors and Corrections in IMDS (March 2022)
Additionally, you can download a description on how you can correct the errors in IMDS.
Over the years, due to changes in the Annex II, some application codes have had to be retired. Even though there is the Recommendation on Change Management, you may have to resubmit.
It is a warning (and you can send the MDS anyway), when the invalid application is included in a referenced component (from your supplier). In this case, the applications are read-only and you can therefore, not change them (e.g. the MDS was sent to you). However, although the IMDS system allows you to send with a warning your customer may choose to not follow Recommendation 022 and require you to resubmit
It is an error (and the application must be changed before sending), when the invalid application ...
- is assigned to a component MDS created by your company or
- was added for an OEM
When calculating the maximum amount of jokers used in a material, IMDS uses "worst case" calculation. The value given as "rest" on the joker substances is not the same as the value used in the warning calculation.
The 10% warning requires a bit of understanding on how the calculations work. For example, if you have a material comprised of substance a, substance b, substance c, and a joker:
- Substance a - range from 25 to 29 - weighted average 27
- Substance b - range from 36 to 40 - weighted average 38
- Substance c - range from 26 to 30 - weighted average 28
- Joker - REST - 7%
- Even though substance a has a weighted average of 27, it COULD have as little as 25% of substance a
- Even though substance b has a weighted average of 38, it COULD have as little as 36% of substance b
- Even though substance c has a weighted average of 28, it COULD have as little as 26% of substance c
So really, for sure, all we know that the total of substance a, b, and c are 87% so the joker could be 13% which is > 10% and sets off the warning.
Additionally, should you use a range on a joker such as Joker - from 9% to 11%, the maximum value of the range is used in the calculation.
To avoid this warning, do not use "rest" on a joker substance.
New checks are implemented in almost every new IMDS release. Until 2008, previously release data sheets were exempt from the new checks and the customer could not easily see the warnings that the supplier was ignoring or for rules that had been implemented after the initial data sheet release. As a response to supplier requests, Release 6.0 brought a complete check of the tree both on the supplier side when releasing/publishing/sending/proposing and on the customer side when accepting. This has resulted in making visible all the warnings on the tree structure and making it easier for a customer to enforce his requirements - thus improving data quality and consistency.
The range warnings and 10% warning was implemented in Release 4.0 (2006).
Recommendation 001 range requirements were published in 2003.
