You said the "error window" doesn't tell you where it's failing... just to be thourough, have you checked the geoprocessing results messages? What about re-opening the model in edit mode, will the "shadows" remain from running it from the toolbox showing where it did sucussfully complete steps? If you've already checked this then I don't know where to go next 😕

Two issues: 1) I'm trying to build a model that will take the table of a feature class and replace certain values in the same feature class. Example: I have [field] with values (coded domains) of -1, 1, 2, 3, 4, X. Every time the coded domain is -1, I want to replace it with X. There are ~15 fields that I want to do this with. Currently I am using Select Layer By Attribute, however this seems to mean that I have to have the layer in the .mxd to use the tool, and I would ideally like to run it from catalog. If I switch to using Select then I get a new feature class of my selection which will not work because in the end I need the whole table (or maybe there is a way it will work that I'm just not aware of yet). Is there another tool to use, or a code block that I can tweak (there has to be...) in the Calculate field tool to select the records I want to change? I'm pretty decent with programming logic, but syntax is another issue entirely. 2) I have a coded domain value of 001, stored as text. I want to create a variable paramater for the model where the input will be exactly 001 and this will be used to calculate the field value. The problem is that every way that I do this the field updates to 1... unless I enclose 001 in double quotes. I was hoping to use the variable for other calculations where the quotes are not neccessary, and it would be best if I didn't need to rely on the user to read instructions about putting this parameter in double quotes (plenty of headaches could be avoided). Any way to do this??

Maybe... I'd like to aggregate some of the data in order to make it meaningful, and have been using SQL in Access with exported tables thus far. I'm just barely breaking into python, I can manipulate scripts and have looked at geoprocessing with arcpy... I guess I was also overlooking doing it in ArcGIS because of the eventual web functionality I want, I hadn't really thought about a service that might have that functionality, maybe a geodata service? It looks like I would have the capability to extract data from there. A majority of my experience with ArcGIS is in ArcMap, all the behind the scenes stuff is pretty new to me. Even my Access, SQL, and VB is from non-GIS applications.

I think what I want to do is use Access to look at the default version* of my SDE, to be able to query the attribute table of one of my feature classes, as well as joining it to an existing Access table. I don't need edit capabilities, just to know that I'm getting the current information when I run a query, I don't even need the spatial data. What I want to do is be able to export snapshots of my attribute data that I can send to owners of the physical roads that I'm mapping so that when their local data doesn't match mine (and they don't have GIS capabilities) I can easily send them a document that will assit in figuring out our discrepancies. I have done a bit of searching here, and it looks like maybe I need to figure out multi-versioned views? Is this neccessary if I don't need to edit the data? I've also seen query layers mentioned a bit, but I'm pretty much at the limit of my GIS and database knowledge right now. My goal is eventually to have a webpage that will have an ArcGIS Online map embedded, and then some way to download the data that I'm trying to query (the real down side to this part is my total lack of web dev experience). *It would be great to be able to look at an editor version in some cases, however if that would make the process much more difficult given the delta tables then I can just continue exporting what I need to Access in those cases.
