AD0223: calculation error: CHG != AVAL - BASE

Hi,

Here is another problem: I am getting this calculation error, CHG is not equal to AVAL-BASE for ADPD dataset. An example: AVAL=100, BASE=100 and therefore CHG=0 in the dataset. Anyone can explain? (I am just guessing it must be decimals I cannot see?).

thanks,
Zsuzsa

SAS value of 0 (zero)

Most importantly, which version of OpenCDISC Validator are you using. We encourage all forum posts to include this info when describing a problem.

We've seen issues with the value of Zero in SAS before. Where zero is actually represented as some really small number like .00000000000n. There's even an engine property of Engine.SasRoundingMode which at one point addressed this. see forum post below. where you could add Engine.SasRoundingMode = Old to the lib/properties/settings.properties file. Although this error sounds like the one we fixed in v1.4.1

2011-03-29 - version 1.3 - Fixed issue where zero value in SAS wasn't actually zero (bug fix)
2011-09-05 Fixed zero handling in SasTransportDataSource. See ticket #42, and forum post http://www.opencdisc.org/forum/ad0011
2013-01-09 Fixed issue where fuzzy equality operator wasn't working for expected RHS values of zero
